Product details

Size No. 8. Drilling range 6.0-30.5 mm. With this robust tool, sheets can be centered, pre-drilled, reamed, and deburred in a single operation. The deeply ground and spiral-shaped cutting groove ensures absolute smooth operation and high cutting performance. In particular, non-breaking chips are transported away cleanly, just like with a spiral drill. This reduces the formation of built-up edges and cold welds on the cutting edges. The cone shape facilitates retraction when drilling through sheets.
